Basic network cat 5 wiring diagram

A simple cat 5 wiring diagram can help us avoid a lot of troubleshooting when it comes to home network wiring. It’s a good idea to test each rj-45 circuit after you terminate the connection ends.

The testers will test each wire channel in the cable. There will be eight channels and all need to be working. The light will scan through each channel, if the channel doesn’t illuminate, you’ll need to do over the connections.

To start out, you’ll need to first run the cat5 cable. Then to terminate the ends, you’ll need to cut or lightly scribe a ring about 1-inch from the end of the cable.

I use a utility knife, then I bend the cable casing so it breaks apart at the cut. There will be a nylon string inside the cable that will get in the way so you need to cut it off.

Now, the cables will be exposed, so put them in order starting with white-orange. See the picture.

OK, so maybe the picture below will show it a little better. Sometimes we have to see it in real life to better understand.

Whoa, the closeup shot looks like a pile of venomous, spitting, cobras!

Sometimes the long wires are unruly, so you need to cut them down to about 1/2-inch. The rj-45 crimper has a special cutter that cuts the wires evenly and straight across.



Push the wires into the rj-45 termination end making sure each wire goes in the order it is supposed to be in.

Next, you can crimp the termination end with the crimper. Squeeze it hard to get a good connection. It’s important to test the connection to make sure you have good continuity on all eight channels. Line testers are cheap and very much worth the money.

Some people say that with wireless routers, CAT-5 wiring is becoming more obsolete. That could be true, but I like to use data pots for added security instead of wireless.

There is also the added advantage of having the wiring in place for home security systems and phone systems. Besides, CAT-5 cable is cheap these days and it only takes about a half day to wire your whole house with cable in each room.

It’s a great idea to plan and diagram your home network ahead of time before you start installing electrical systems.

I just wanted to say that I love your website. My husband and I followed your instructions on building our own home. Most of the work we did ourselves, but not all. We saved $90,000 in labor costs and now have a beautiful home that we own.

I built my own home doing all my own labor. My house costs me around $70,000 for materials. It took me 8 months to build and is about 2,000 square feet. I didn't think I could do it, but your house web site encouraged me. I used all the info you had.

Thank you,

I can't thank you enough for your free information web site about home building. I was looking for Electrical wiring diagrams when I found your site. It was very helpful.

My wife and I lost our home to foreclosure but we kept a plot of land to start over. We are halfway through the construction of our house. Your website gave us hope to start over and build a house with low payments. We are in our late 60's but we find it rewarding to put so much effort into a project that will reward us for years to come.
